web container: Warning: World-writable config file '/home/.my.cnf' is ignored

[rfay]

Describe the bug

/home/my.cnf doesn't work if writeable, and we have ended up with it writeable.

Warning: World-writable config file '/home/.my.cnf' is ignored

To Reproduce

ddev ssh
mysql
Warning: World-writable config file '/home/.my.cnf' is ignored
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

Expected behavior

Connect to the mysql db named 'db'

Actual behavior:

Warning: World-writable config file '/home/.my.cnf' is ignored
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

The workaround:
Use mysql -udb -pdb -h db db
or
sudo chmod ugo-w ~/.my.cnf
